The LED lights are dimmable warm white 150 Lumen and 2 Watt color 2200 Kelvin. Lifespan approx. 10,000 burning hours. You do need a Dimmer 0-35 Watt-Phase cut. A phase-AF cutting and a dimmer that measures from 0 so 0-35 Watt would be good, after all, a chandelier with 12 lights contains only 24 Watt. We have good experiences ourselves with the dimmers of 123LED that are around 30 euros.
